ABSTRACT:
A microprocessor is provided for supporting reduction of codes in size, wherein instructions are extended in units of 0.5 word from a basic one word code. A word of instruction, fetched from an external memory, is transferred to a decoding register via instruction buffers and a selector both operate in units of half words, then is decoded by a decoder. A storage unit stores a state of an instruction stored in an instruction buffer. A controlling unit controls the selector so that the instructions are transferred from instruction buffers to the decoding register in units of half words based on a direction from the decoder and the states stored in the storage unit.
